Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 71 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 71 }$: $ x^{2} + 69 x + 7 $
Roots:
$r_{ 1 }$ $=$ $ 19 a + 42 + \left(20 a + 53\right)\cdot 71 + \left(41 a + 47\right)\cdot 71^{2} + \left(26 a + 60\right)\cdot 71^{3} + \left(21 a + 45\right)\cdot 71^{4} +O\left(71^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 21 + 13\cdot 71 + 55\cdot 71^{2} + 8\cdot 71^{3} + 34\cdot 71^{4} +O\left(71^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 34 a + 31 + \left(49 a + 32\right)\cdot 71 + \left(35 a + 23\right)\cdot 71^{2} + \left(57 a + 50\right)\cdot 71^{3} + \left(2 a + 70\right)\cdot 71^{4} +O\left(71^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 13 + 12\cdot 71 + 2\cdot 71^{2} + 33\cdot 71^{3} + 52\cdot 71^{4} +O\left(71^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 37 a + 28 + \left(21 a + 26\right)\cdot 71 + \left(35 a + 45\right)\cdot 71^{2} + \left(13 a + 58\right)\cdot 71^{3} + \left(68 a + 18\right)\cdot 71^{4} +O\left(71^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 52 a + 9 + \left(50 a + 4\right)\cdot 71 + \left(29 a + 39\right)\cdot 71^{2} + \left(44 a + 1\right)\cdot 71^{3} + \left(49 a + 62\right)\cdot 71^{4} +O\left(71^{ 5 }\right)$
